Overwing

State of agent readiness

Can an agent use a developer tool? Measured every week.

Developer-tool companies checked with Beacon every week, one seventh of the list each night, so the readiness of the sector can be followed over time. Chosen on 2026-10-01 as products that sell to developers or to agents; not a random sample. Each site gets the same Beacon check: whether an agent can find it, read it and use it. Below: the last seven days against the seven before.

Each site

The aggregates above are public. The score of each named site is shown to signed-in users, so a company’s result is read by someone, not indexed. Create a free account or sign in.

The panel is a chosen list, not a sample of the industry: 69 products that sell to developers or to agents, picked on 1 October 2026. A seventh of the list is checked each night, so “this week” is every site’s latest check in the last seven days. Checks are read-only, about twenty requests per site, identified as OverwingBeacon.
